Specification of Letters Patent.

Patented sept. 29, 1914.

Application led July 5, 1913. l Serial No. 777,409.

To all 'whom t may concer/ri: ,j

Be it known that I, HENRY H. DUPONT, a citizen of the United States, residing at lndianapolis, in the county of Marion and State of Indiana, have invented anew and useful Shower-Stall, of which the following is a specification.

The object of my invention is toproduce a sanitary shower readily erected for use, either 1n new or old buildings, said stall4 consisting of' enameled cast iron sections which may be erected without the use of' fastening devices contacting with the enameled surfaces.

The accompanying drawings illustrateE my invention. l Figure 1 is a perspective view of thatl tion within a recess or pocket formed inI a wall or partition Fig. 2 a central vertical section of, the structure shownv in Fig. 1;-

shown in Fig. 4; Fig. 6 a detail of the joint between two of the adjacenttop members; 7 a detail of a desirable form of joint' Fig. between one of the wall members andv the forward yfinishing plate; Fig. 8 a fragmentary section of the joint between a top plate and a vertical plate; Fig. 9 a fragmentary sectional detail of the joint betweenl one vor' the vertical plates and the receptor; Fig. 10

a fragmentary horizontal section of a de sirable joint between two lvertical members; and Fig. ,'11 a horizontal fragmentary section ofthe joint between one ofthe vertical members and a front finishing plateJof-the form -shown in Fig. 5.

In the drawings 10'indicates the slightly dished-bottom-.plate of a receptor convenwith a verticaliange or rim ormsthe support for the structure and the upper end of which is projected suiliciently `above the bottom 101:0 form a container of adequate volume to insure'againshany 4overflow. At the front of the basin the upper edge of -lange 11 is vturned outwardlyand,

downwardly, as indicated at 12, so that an arc-shaped finishing .plate 13, with side Wings 14, 14, may be projected thereunder. Beginning at each end .of the vdown-turned bath stall which may be.

device constructed Jfor erecoutwardly displaced and then upwardly ex- Bottom 10 is provided with a suitable outlet 10 adaptedto be connectedl with the' upper end of the wastevpipe 10; Lip 12 is .purposely lower than the part 15 so that incase of acidental overflow, it will take place in front of the device where it will be immediately visible.

The receptor -just described 'is made of cast iron and the upper surface of bottom 10 and the inner surface of flange 11, together with the upper and outer surface of lip 12, is enameled or glazed in the usual manner of glazing bath-room articles, but it is a well known fact that in producing articles of this kind it is practically impossible to 'glaze under surfaces or :to glaze both` outer and inner surfaces of a vertical` flange or member. It is for this reason that I provide the lip 12 which is sufficiently separated fromy the main body of they iange 11 topermit the insertion of theplate 13, as

receptor 10 Amay extend only to the lower edge of lip.

of the plate 13 and'wings 14.

18 each ofv which -at its lower end is pro. vided upon -its rear and outwardl extending finger or flange 19 which is sucien'tly separatedr from thev lower end ofthe main body of theplate to not only receive the upwardly projecting portion 15,0f flange 11 but also to receive a pack`ing`20 of putty orl other vsuitable sub-- stance. v v The joint just 'describedholds .the lower ends of the vertical 4wall sections in proper position and their adjacentedges are connec'ted by a somewhat similar joint but, in order that the vertical edges of the sections shall not be' too noticeable fromlthe entrance opening of the stall the Vsections 16 and 18 are mates, right and left, each of said sections at its rear vertical edge being provided on its back with a finger 22 spacedv from the main body ofv the plate so4 as to form ag pocket 23 vfor the reception of the adjacent edge of the plate 17 and also so as to receive a packing 24. By this arrangement, an

accidental leakage' into this joint will flow by thls arrangement the -enameling of the:

portion the upper edge of flange 11 is tended, asindicated at 15, Figs. 2 and 9. i.

12 and the desired finish below this lip is obtained by thel glazed outer -face face witha downwardly The vertical wallof the stall is Couven-H35 iently formed in' several sections 16, 17 and downwardly and, striking the upper edge of part` 15 of ange 11 at its inner face, will flow down into the receptor.

The upper ends of the vertical wall plates are held together by the top plates 25, 25, 26, 26, each of which is provided with a down-turned flange 27 lying inside of the vertical wall plates and having their vertical faces enameled as indicated in Fig. 8.v Each of the top plates is also provided on its. under face with one or more downwardly extending lugs 28 which are spaced apart from the flanges 27 a distance suiicient to permit the insertion of the upper ends of the vertical plates 16, 17.01* 18.y At their adjacent portions the plates and 26 are formed to overlap as indicated in Fig. 6, the arrangement being such that all exposed faces of these plates may be readily enameled by the present known processes. The top plates 25, 25 do not meet each other but arev spaced apart a distance substantially the same as the distance between the forward vertical edges of the plates 16 and 17 and at their adjacent corners ,these plates are provided with short vertical pins 30 overwhich may be sleeved the ends of a curtain rod 32, this curtain rod thus form-y lng a chord to that portion of the ar'c of the -receptor' which is providedwith the .finishing lip 12. The forward vertical flanges of the plates 25, 25, overlie the upper ends of the finishing plates 33, 33 each of which at its lower end is provided at the rear with a flange or Vfinger 19 so as to overlie the upper edge of the adjacent wing 14. The outer edge of each plate 33 is adapted to.be slightly buried in the adjacent wall of the pocket or recess 34 (indicated in dotted lines in Fig. 3) while the inner edge is curled lrearwardly and 'outwardly as indicated" at 35 Fig. 3 to receive the forward edge of the vertical plate 16 or 18, as indicated in Fig. 7.

The finishing plates 33 (Fig. 5), are practically the same as finishing plates 33 4except that they need to be wider and, be-

cause they .lie substantial y tangentially to1 lthe adjacent plate 16 or 18, the. edge 35A is preferably of the form shown' in Flg. 11V the outer face of the vertical wall 16 being ground away, as indicated at 36 (Fig. 11), beforethe wall 16 is enameled on its inner face. This preliminary grinding makes room for the packing'37.

In order to make the structure more rigid, although not absolutely necessary, I provide the rear faces of the vertical wall sections, nearv their adjacent edges, with rearwardly extending flanges 38 which are perforated to receive clampmg bolts 39. vThese flanges prevent warping of the plates during enameling. v J l In order to insure against discharge of water from the stall the spray nozzle 40 fwise 1nj ure ,conveniently brought up in the space behind one of the finishing plates 33, said iinishing plate being provided with an opening 43 through which the controlling valve 44 may operate. The usual stop valves may be placed within the supply pipes and rendered accessible through comparatively small openings 45 in the nishing plate 33.

y he receptor, the vertical walls and the top plates are to be formed of cast iron and the several exposed faces yare subjected to a common enameling process such as used in the production of bath tubs of a well known type, and it will be noted that the formation of the various parts is such that 4only those surfaces are exposed to view and to the action of the water as can be readily and adequately enameled in the manner described. In erecting the structure a special recess, as indicated by dotted lines in Fig. 3, or the structure may be mounted in a corner as indicated in Fig. 5, and the receptor will be connected to the waste pipe, said waste pipe serving to retain the receptor in proper position. The other portions may be asse1nbled, in the manner set forth, without the use of any clamping or fastening means which will be at all liable to crack or otherthe enameled surfaces. The

structure may be readily erected in existing 4 rooms and is entirely sanitary. By arranging the curtain rod 32 as a chord-to the exposed arc of the receptorto the entrance, the lower end of the curtain will lie entirely within the receptor and thus prevent -any dropping or splashing on the floor outside of the structure. It will also be apparent that the user may completely regulate the liow of water without being wet during the operation.
